Have you ever wondered which recovery method to apply in any given case?

The obvious approach is first to understand how effective the various drive mechanisms are. ExcSim does that for you. ExcSim automatically gives you both the daily and cumulative effectiveness of the drive mechanisms, as shown below.

Of course ExcSim can handle saturated oil reservoirs with a gas cap. The pictures and video above demonstrate exactly that.

Note that ExcSim also reports tabulated average values of Bo, Bg, Bw, Rs, and Rv as part of the material balance report. In Excel you can combine these with the reservoir offtake or expansion terms to get your own 'personalized' output tables.
